Description

State of the art

The invention relates to a method for the allocation of telecommunications services according to the preamble of the main claim.

From the GSM (Global System for Mobile Communications) specification 02.11, version 4.9.0 it is known to associate mobile stations with user classes. At the same time the user classes divide the amount of mobile stations randomly in ten classes. A base station can now grant or deny permission for each of these user classes on one random access channel to send request messages. The permission grant or denial is given to the mobile stations by means of a signaling channel communicated.

From EP 0 658 014 A1 a cellular telecommunication system is known in which Orbital satellites Assign communication channels to nodes in cells. Each subscriber unit is programmed with a class identifier. In periods when it is desirable to access a satellite on some restricted classes or Class limits, the satellite sends a list of locked class identifiers, which only allow such participants access to the communication system, whose classifiers are not on the list of locked classifiers. The For example, periods of limitation of access to the satellite may be periods of time be high load.

From US 5,313,653 it is known that a resource allocator provides new service messages sends to the communication units, if the corresponding communication unit a new service is assigned or a change in the services allowed takes place.

Advantages of the invention

The inventive method with the features of the main claim has the other hand the advantage that information signals to the at least one subscriber station containing information about which of the telecommunications services the at least one Subscriber station are allocated for use. To this Way is a more flexible allocation of Telecommunications services to the at least one Participant station possible. This more flexible allocation of Telecommunications services not only see the possibility an allocation of all telecommunications services or absolutely no telecommunications service to the at least one subscriber station before, but also the Allocation of a part of available Telecommunications services to the at least one Subscriber station. Resources of the telecommunications network can be more effective in the subscriber stations of the Telecommunications network are provided so that certain telecommunications services take longer provided at least one subscriber station can be.

By the measures listed in the dependent claims are advantageous developments and improvements in the Main claim specified method possible.

It is advantageous that at different times different Telecommunication services of at least one Be assigned to the subscriber station. That way you can the resources of the telecommunications network even more effective and more flexible the at least one subscriber station be dynamically allocated for use.

It is particularly advantageous that the Telecommunication services of at least one Subscriber station depending on Message traffic in the telecommunications network be assigned. In this way, even at high Message traffic in the telecommunications network certain telecommunications services through targeted Forbid other telecommunication services longer provide at least one subscriber station.

Further flexibility of the allocation procedure Telecommunications services and thus resources of the Telecommunications network results in an advantageous manner by the division of the subscriber stations in User classes, the telecommunications services providing the Subscriber stations depending on their user class be assigned.

Another advantage is that the at least one Subscriber station through the information signals, preferably by means of a bit pattern, is communicated which telecommunication service or combination of Telecommunications services from a predetermined amount at least one telecommunication service and / or at least one combination of telecommunication services the at least one subscriber station is assigned. On In this way, the information signals require a minimum Amount of data and therefore claim for your transfer less time with unchanged data rate or a lower one Data rate with unchanged transmission time.

Description of the embodiments

In Fig. 1, 100 indicates a base station as one Mobile network trained telecommunications network. One such mobile network is usually cellular, wherein each radio cell of the mobile network of a Base station is supplied. The base station 100 thus spans a radio cell in the mobile network, in the according to FIG. 1 a first subscriber station 5, a second Subscriber station 10, a third subscriber station 15 and a fourth subscriber station 20 are arranged. Both four subscriber stations 5, 10, 15, 20 should be exemplary mobile stations, such as Mobile phones, radiotelephones, or the like act. at The embodiments described here should therefore the first subscriber station 5 as the first mobile station, the second Subscriber station 10 as a second mobile station, the third Subscriber station 15 as the third mobile station and the fourth Subscriber station 20 is formed as a fourth mobile station be. A network operator of the mobile network offers a specified number of telecommunication services. in the following are three different examples Telecommunication services are offered by the network operator can. It can act as a first Telekummunikatonsdienst for example, a data usage service may be provided, which are used by the mobile stations 5, 10, 15, 20 can transmit short bursts of data to base station 100 over a random access channel 30, hereinafter exemplarily designed as RACH (Random Access Channel) should be, transfer. As a second Telecommunications service, for example, a Capacity requirement service be provided, in which the RACH 30 are used by the mobile stations 5, 10, 15, 20 allowed to separate data channels for data transmission to request. As a third telecommunications service can For example, be provided a voice call service, in which the RACH 30 is used by the mobile stations 5, 10, 15, 20 may be used to initiate voice transmissions or continue. The three telecommunication services can individually and / or in any combination Mobile stations 5, 10, 15, 20 from the network operator for use be assigned.

The telecommunications services have to be covered by the corresponding mobile station via the base station 100 at Network operators are requested. The Telecommunications services will be provided via RACH 30 Mobile stations 5, 10, 15, 20 made accessible. On the RACH 30 can usually receive messages from several Mobile stations are sent to the base station 100. On This way you can read messages from different mobile stations collide with each other. The base station 100 confirms therefore duly received messages in which they corresponding confirmation or acknowledgment information on another channel, not shown in FIG. 1, for example, a paging channel, to those Mobile stations resend their messages received properly. The telecommunications services are usually via the RACH 30 from the mobile stations 5, 10, 15, 20 requested or made accessible.

In the event that the message of a mobile station on the RACH 30 collides with another message, finds no proper reception of this message in the base station 100 instead, so that the base station 100 also no Confirmation information to the corresponding mobile station can resend. The mobile station therefore sends for one given time in which no confirmation information from the base station 100 was received, the message again via the RACH 30 to the base station 100. In this way threatens an overload of the RACH 30, thus the user-initiated request from Telecommunications services through the corresponding Mobile stations due to its limited transmission capacity limited.

Overloading the RACH 30 can thus be avoided that the network operator the use of the Telecommunication services for the individual mobile stations 5, 10, 15, 20 via the RACH 30 specifically restricts. there For example, individual telecommunications services can only for certain user classes of mobile stations temporarily or permanently privileged. According to the described embodiments of Figure 1 a first user class 35 is provided, which is the first Mobile station 5 and the second mobile station 10 includes. Furthermore, a second user class 40 is provided, the the third mobile station 15 and the fourth mobile station 20 includes. However, it can also be provided for each Mobile station to provide its own user class. It could also be provided, user classes with different Number of mobile stations. It continues possible, more than two mobile stations in a user class provided. The network operator can now the Telecommunication services to the individual mobile stations in Dependence of their affiliation with one of the two Assign user classes 35, 40. That means the two Mobile stations 5, 10 of the first user class 35 same Telecommunication services allocated by the network operator become. In an analogous manner, the mobile stations 15, 20 of the second user class 40 same Allocated to telecommunications services. The mobile stations 5, 10 of the first user class 35 assigned Telecommunication services can be different from the Mobile stations 15, 20 of the second user class 40 differentiated telecommunications services. The the mobile stations of the two user classes 35, 40th However, allocated telecommunications services can also be equal. The network operator informs the individual Mobile stations 5, 10, 15, 20 by information signals, the from the base station 100 to the respective mobile station 5, 10, 15, 20 are transmitted, which is the Telecommunication services of the network operator of corresponding mobile station 5, 10, 15, 20 are allocated. This becomes representative of all mobile stations 5, 10, 15, 20 below on the basis of the allocation of Telecommunications services of the network operator to the first Mobile station 5 described in accordance with Figure 1.

At this time, the base station 100 transmits at predetermined times Information signals to the first mobile station 5. The Information signals can according to Figure 1 via a Signaling channel 25, which in the following example as broadcast control channel BCCH should be trained be transmitted. It is with the information signals at the given times in each case a bit pattern to the first mobile station 5 transmitted. The bit pattern can be in one first embodiment contain information about which telecommunication service and / or which combination of telecommunications services from a predetermined amount of telecommunication services of the first mobile station 5 is allocated. For the given amount of Telecommunications services are the telecommunications services already described, such as Data usage service, capacity request service and Sprachrufdienst. Because the bit pattern is not just the first Mobile station 5, but also to all other mobile stations 10, 15, 20 also via the signaling channel 25, the as described as BCCH and thus as a point-to-multipoint channel is formed so that all mobile stations the same information received at the same time, sent will give them those assigned to them Communicate telecommunications services includes the bit pattern the allocated telecommunications services for each User class 35, 40. The associated bit pattern is shown in FIG. 2 represented and designated by the reference numeral 45. It includes a first bit pattern section 105 for the first one User class 35 and a second bit pattern portion 110 for the second user class 40. Both bit pattern sections 105, 110 each comprise 3 bits. A first bit 51 of the first Bit pattern portion 105 of the first bit pattern 45 is thereby whether the data usage service the mobile stations 5, 10th the first user class 35 is assigned. A second bit 52 of the first bit pattern portion 105 of the first bit pattern 45 indicates whether the capacity request service is using the Mobile stations 5, 10 of the first user class 35 assigned is. A third bit 53 of the first bit pattern section 105 of the first bit pattern 45 indicates whether the voice call service uses the Mobile stations 5, 10 of the first user class 35 assigned is. A first bit 61 of the second bit pattern portion 110 of the first bit pattern 45 indicates whether the Data usage service to the mobile stations 15, 20 of the second User class 40 is assigned. A second bit 62 of the second bit pattern portion 110 of the first bit pattern 45 Indicates whether the capacity request service is using the Mobile stations 15, 20 of the second user class 40 assigned is. A third bit 63 of the second bit pattern portion 110 of the first bit pattern 45 indicates whether the mobile stations 15, 20 of the second user class 40 of the voice call service assigned is. A logical one of the respective bit indicates that the corresponding telecommunications service the corresponding Assigned to mobile stations and indicates a logical zero, that the corresponding telecommunications service the corresponding mobile stations is not allocated. According to FIG. 2 are in the first bit pattern section 105 of the first one Bit pattern 45, the first bit 51 and the second bit 52 on One is set and the third bit 53 is set to zero. The means that the mobile stations 5, 10 of the first User class 35, the data usage service and the Capacity Request Service and the combination of assigned to both services. The voice call service is however, the mobile stations 5, 10 of the first user class 35 not assigned. In the second bit pattern portion 110 of FIG first bit pattern 45 are the first bit 61, the second bit 62 and the third bit 63 are each set to one. The means that all three telecommunications services and all possible combinations of two or three Telecommunications services the mobile stations 15, 20 of the second user class 40 are assigned. On the basis of a Users of the corresponding mobile station in the mobile station introduced access card on which the User class of the mobile station is stored, recognizes the Mobile station their affiliation to the corresponding User class and can therefore be targeted to the associated Access bit pattern portion of the corresponding bit pattern, around the ones assigned to him in this user class Telecommunications services and / or combinations Telecommunications services. The allotted Telecommunication services may be the appropriate Mobile station then use the RACH 30, as shown in FIG 1 is illustrated by the first mobile station 5, the News about the use of her assigned Telecommunication services via the RACH 30 to the Base station 100 transmits. According to Figure 2 are for each User class requires three bits to count at a number of three telecommunication services of the respective mobile station tell which of the three telecommunications services you have alone or in any combination. For two classes of users therefore gives the length of the first Bit pattern 45 to 2 x 3 = 6 bits. Generally, the calculated Length of the first bit pattern 45 from the product of the number the user classes and the number of possible ones Telecommunications services.

In the case where a bit pattern portion of the first Bit pattern 45 contains only a single bit, that on one is set is only the associated telecommunications service associated with the corresponding mobile station, wherein Combinations with other telecommunication services are not possible because their bits are set to zero.

Another embodiment for forming a Bit pattern for the allocation of telecommunication services to a mobile station is shown in FIG. The above the signaling channel 25 transmitted information signals comprise a second bit pattern 50, that of the first Mobile station 5 tells which telecommunication service or which combination of telecommunications services a predetermined amount of at least one Telecommunications service and / or at least one Combination of telecommunications services of the first Mobile station 5 is assigned. The same applies to the Allocation of telecommunications services or combinations from telecommunications services to the other mobile stations 10, 15, 20. In this case, all mobile stations 5, 10, 15, 20 a second bit pattern 50 via one each Signaling channel transmitted, the first Bit pattern portion 115 for the first user class 35 and a second bit pattern portion 120 for the second one User class 40 includes. The first mobile station 5 and the second mobile station 10 therefore receive information about the their assigned telecommunications services through evaluation of the first bit pattern portion 115 of the second bit pattern 50 and the third mobile station 15 and the fourth mobile station 20 receive information about their assigned Telecommunication services by evaluation of the second Bit pattern portion 120 of the second bit pattern 50. The first Bit pattern portion 115 of the second bit pattern 50 includes a first bit 71 and a second bit 72. The second one Bit pattern portion 120 of the second bit pattern 50 includes also a first bit 81 and a second bit 82. According to FIG. 3 is the first bit 71 of the first bit pattern section 115 of the second bit pattern 50 is set to zero and that second bit 72 of the first bit pattern portion 115 of the second Bit pattern 50 is set to one. The first bit 81 of the second bit pattern section 120 of the second bit pattern 50 is set to one and the second bit 82 of the second Bit pattern portion 120 of the second bit pattern 50 is on Zero set.

According to the second embodiment, a lot of a telecommunications service and two combinations of Telecommunication services for allocation to the Mobile stations 5, 10, 15, 20 may be provided. Includes this amount in the described embodiment the Voice call service as the first set element, the combination from voice call service and capacity request service as second quantity element and the combination as Voice Call Service, Capacity Request Service and Data usage service as the third set element. Only each a set element can be the corresponding mobile station be assigned. The number of this quantity element becomes doing binary through the 2 bits of each Bit pattern portion of the second bit pattern 50 shown. According to the embodiment of Figure 3 is thus the Mobile stations 5, 10 of the first user class 35 due to the Bit combination 0-1 in the first bit pattern section 115 of the second bit pattern 50, d. H. a binary one the first Quantity element, so allocated only the voice call service. The mobile stations 15, 20 of the second user class 40 however, due to the bit combination 1-0 in the first one Bit pattern portion 115 of the second bit pattern 50, d. H. a binary two the second set element and thus both the voice call service as well as the Capacity request service allocated for use. Of the Quantity could still be a fourth quantity element with the Bit combination 0-0 can be added without the number of bits per bit pattern section would have to be increased. For a lot with a maximum of four sets of elements, each user class has 2 bits for displaying the allocated quantity element required, so that in the second embodiment according to Figure 3 in two classes of users the length of the second Bit pattern 50 2 x 2 = 4 bits. General results the length of the second bit pattern 50 according to the second Embodiment of the product of the number of User classes and to the next larger integer Rounded two-logarithm of the number of Set elements.

The information signals are supplied from the base station 100 the mobile stations 5, 10, 15, 20 at predetermined times, preferably transmitted at regular intervals. Of the Network operator can use the telecommunication services in Dependence of the message traffic volume in Telecommunications network and thus in dependence of a expected utilization of the RACH 30 the individual Mobile stations 5, 10, 15, 20 depending on their Allocate user class and thereby certain Telecommunications services of a given user class or certain classes of users temporarily or permanently to provide privileged. Since that is Message traffic in the telecommunications network with As time changes, so does the expected change Utilization of the RACH 30 over time, so that usually too different times different telecommunications services by means of correspondingly changed bit pattern assignment the Mobile stations 5, 10, 15, 20 are assigned. The from the GSM specification 02.11, version 4.9.0 known case of Allocation of all telecommunications services or alternatively no telecommunications service to the appropriate Mobile stations 5, 10, 15, 20 represents a special case of According to the invention. Become a User class all telecommunications services allocated, Thus, according to the embodiment of Figure 2 all Bits of the associated bit pattern section are set to one. Will the mobile stations of a user class no Telecommunications service allocated, are in accordance with the Embodiment of Figure 2 all the bits of corresponding bit pattern section set to zero.

A relief of the RACH 30 can additionally be achieved be that a repeat counter and / or a Repeat distance is provided. The repeat counter gives the maximum number of allowed retry attempts for a repeated submission of a message from the corresponding mobile station via the RACH 30 to the Base station 100 in the event of a collision with a Message from another mobile station. Of the Repeat distance is a stochastic measure for that time interval until the next repetition of the respective mobile station to the base station 100 via the RACH 30 sent message. The smaller the number of allowed retries and the larger the Repeat distance, the greater the relief of the RACH 30. The repeat counter and / or the Repeat distance can be at regular intervals along with the bit pattern of the allocated ones Telecommunication services to the corresponding mobile stations optionally together with other radio cell-specific Information on the associated signaling channel 25 be communicated.

The inventive method can be in a mobile network according to UMTS standard (Universal Mobile Telecommunication System), implemented according to GSM standard, or the like become.

The inventive method is not on the application limited in a mobile network, but generally in Telecommunication networks for the allocation of Telecommunication services to subscriber stations of Telecommunications network applicable, the Telecommunications network, for example, a can be wired landline.
